I think we're beating this one to death. I think the thread starter got his answer and has disappeared by now, hehe
Anyway, the rules have been explained, it's been explained when/where/how/why different methods are used, how to modify the settings to be more ANSI compliant, and what happens under the most recent MSVS compiler.
I guess the only thing left is a group hug and then its off to new threads!:wave:

IT IS BETTER TO DECLARE THE VARIABLE INITIALLY.
In C++ it is always better to declare a variable as close as possible to the point of first use for the simple reason that you don't want to call a constructor (and later call a destructor) if it's not necessary.
While in some of these simple examples it isn't going to matter (an int's constructor is trivial and there is nothing else between the declaration and the for, so the int gets constructed whichever way you do it), it is good practice not to declare things until you need them. One day your constructor is going to cost you time!

I disagree - that's a performance consideration at the expense of readability and hence maintainability.
It's a personal/business/application choice. There are pro's and con's to both.

What else can be said about declaration in for loop ? :D
Can the moderators change the title of this topic? Pretty weird to have 20 answers for a Simple question on a For Loop
I wonder if this was an Ammazingly difficult question on a For Loop?
:D
The question was simple enough :p.
No but we can close the thread since it's running into the land of off-topicness (that's from 7th century mickalise)Quote:
